Definitions

  • the present invention relates to a camera having a photographing lens-driving device operated by the electromagnetic force for focusing and a driving device operated by the electromagnetic force for the control of an exposure amount.
  • the former further includes a method wherein the photographing lens, like the one used in a lens-shutter camera, is energized with a spring to the position of infinity when the film is wound up after the completion of photographing and then the photographing lens is drawn out for photographing by the motor up to the position required by a measured-distance signal and a method wherein the amount of rotation of the motor and the direction of rotation are changed by the measured-distance signal, as seen in the AF device of a single lens reflex camera, thereby the photographing lens is moved, both of which require the addition of gear reduction device and of a device that converts the revolving motion to the rectilinear motion and therefore it is becoming hard to incorporate the former into the latest camera that is moving toward a trend of small size and light weight.
  • the holding frame for the permanent magnet and the lens holder for the photographing lens are separate each other regardless of whether the electromagnetic driving device is for shutter-driving or for photographing lens-driving.
